BMW will unveil a small Zero Emissions Vehicle (ZEV) sometime in 2012. Supposed to be called Isetta, the future tiny car was created because of new Californian regulations which require big car makers to sell between a few hundred and a few thousand ZEVs every year from 2012.

BMW chief Norbert Reithofer recently said the company “would be obliged to sell a Zero Emissions Vehicle under the US regulations and that a battery car was “the most likely answer”.

Reithofer also said that BMW could have built just a few hundred cars to meet the US regulations but admitted that the company was also wondering if it could use the basic concept “not just for an electric car but also for a range of city cars”. These cars would use petrol and diesel motors, and could even feature BMW motorcycle engines.
